MurPhiller is a family of radiopharmaceutical dispensing systems.
The heart of the project is the Patented detector, called STEM CHAMBER.
The particular and unique shape of the STEM CHAMBER allows to reduce the dimensions of the device, to have an optimal accuracy, in order to maximize the ergonomics.
Main components
The MurPhiller dispensing unit is composed of two main components:
The filling unit is responsible for determining the activity set by the user for the filling of the syringe and for performing the exact filling in the shielded syringe/vial.
The unit has an internal microprocessor based electronics, including a dedicated firmware, performing all the tasks required for the syringe/ vial filling.
Its main components are:
- Physio holder: this is where the saline solution is placed
- Physio pump: is the high speed peristaltic pump responsible for pushing saline solution into the syringe or vial
- Syringe/vial sliding holder: holder for syringe/vial housing
- Radiopharmaceutical pump: is the low- speed peristaltic pump, responsible for pushing the radioactive compound into the syringe/vial
- Measuring chamber for syringe/vial:
dedicated measuring chamber where the destination syringe/vial is placed. It is responsible for measuring the activity that is going to be dispensed in the syringe or vial
- Integrated measuring electronics: long life remotized electronics control board.
